The Siemens SENTRON 3VA2216-8JP32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed as the cabinet heats up. Its interrupting capacity hits 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V — numbers that put it squarely in high-fault-duty territory for industrial mains or large sub-distribution. The ETU550 electronic trip unit gives you adjustable long-time delay (tr from 0.5 to 25 s) and short-time delay (tsd up to 0.5 s), so you can shape the curve for selective coordination downstream. Communication function is built in, which means it can talk to a higher-level system for metering or remote trip indication — useful if you're integrating into a BMS or SCADA layer.
Dimensions are 86 mm deep, 105 mm wide, and 181 mm tall — a standard SENTRON 3VA frame size that drops into existing 3VA panel cutouts without modification.
